The XICS-on-XIVE KVM devices now has an attribute to configure the number
of interrupt servers. This allows to greatly optimize the usage of the VP
space in the XIVE HW, and thus to start a lot more VMs.
Only set this attribute if available in order to support older POWER9 KVM
and pre-POWER9 XICS KVM devices.
The XICS-on-XIVE KVM device now reports the exhaustion of VPs upon the
connection of the first VCPU. Check that in order to have a chance to
provide a hint to the user.

The XIVE and XICS-on-XIVE KVM devices on POWER9 hosts can greatly reduce
their consumption of some scarce HW resources, namely Virtual Presenter
identifiers, if they know the maximum number of vCPUs that may run in the
VM.
Prepare ground for this by passing the value down to xics_kvm_connect()
and kvmppc_xive_connect(). This is purely mechanical, no functional
change.

The TIMA operations are performed on behalf of the XIVE IVPE sub-engine
(Presenter) on the thread interrupt context registers. The current
operations supported by the model are simple and do not require access
to the controller but more complex operations will need access to the

When the XIVE IVRE sub-engine (XiveRouter) looks for a Notification
Virtual Target (NVT) to notify, it broadcasts a message on the
PowerBUS to find an XIVE IVPE sub-engine (Presenter) with the NVT
dispatched on one of its HW threads, and then forwards the
notification if any response was received.
The current XIVE presenter model is sufficient for the pseries machine
because it has a single interrupt controller device, but the PowerNV
machine can have multiple chips each having its own interrupt
controller. In this case, the XIVE presenter model is too simple and
the CAM line matching should scan all chips of the system.
To start fixing this issue, we first extend the XIVE Router model with
a new XivePresenter QOM interface representing the XIVE IVPE
sub-engine. This interface exposes a 'match_nvt' handler which the
sPAPR and PowerNV XIVE Router models will need to implement to perform
the CAM line matching.

The BMC of the OpenPOWER systems monitors the machine state using
sensors, controls the power and controls the access to the PNOR flash
device containing the firmware image required to boot the host.
QEMU models the power cycle process, access to the sensors and access
to the PNOR device. But, for these features to be available, the QEMU
PowerNV machine needs two extras devices on the command line, an IPMI
BT device for communication and a BMC backend device:
-device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10
The BMC properties are then defined accordingly in the device tree and
OPAL self adapts. If a BMC device and an IPMI BT device are not
available, OPAL does not try to communicate with the BMC in any
manner. This is not how real systems behave.
To be closer to the default behavior, create an IPMI BMC simulator
device and an IPMI BT device at machine initialization time. We loose
the ability to define an external BMC device but there are benefits:
- a better match with real systems,
- a better test coverage of the OPAL code,
- system powerdown and reset commands that work,
- a QEMU device tree compliant with the specifications (*).
(*) Still needs a MBOX device.

pnv_xive_vst_size() tries to compute the size of a VSD table from the
information given by FW. The number of entries of the table are
deduced from the result and the MMIO regions of the ESBs and the END
ESBs are then resized accordingly with the computed value. This
reduces the number of elements that can be addressed by the ESB pages.
The maximum number of elements of a direct table can contain is simply:
Table size / sizeof(XIVE structure)
An indirect table is a one page array of VSDs pointing to subpages
containing XIVE virtual structures and the maximum number of elements
an indirect table can contain :
(PAGE_SIZE / sizeof(vsd)) * (PAGE_SIZE / sizeof(XIVE structure))
which gives us 16M for XiveENDs, 8M for XiveNVTs. That's more than the
associated VC and PC BARS can address.
The result returned by pnv_xive_vst_size() for indirect tables is
incorrect and can not be used to reduce the size of the MMIO region of
a XIVE resource using an indirect table, such as ENDs in skiboot.
Remove pnv_xive_vst_size() and use a simpler form for direct tables
only. Keep the resizing of the MMIO region for direct tables only as
this is still useful for the ESB MMIO window.

The current code assumes that the fields of the NVT structure is

Failing to set any of the ICS property should really never happen:
- object_property_add_child() always succeed unless the child object
already has a parent, which isn't the case here obviously since the
ICS has just been created with object_new()
- the ICS has an "nr-irqs" property than can be set as long as the ICS
isn't realized
In both cases, an error indicates there is a bug in QEMU. Propagating the
error, ie. exiting QEMU since spapr_irq_init() is called with &error_fatal
doesn't make much sense. Abort instead. This is consistent with what is
done with XIVE : both qdev_create() and qdev_prop_set_uint32() abort QEMU
on error.

File tests/acceptance/linux_ssh_mips_malta.py is crucial for
entire MIPS platform, so add it to the MIPS section. The
maintainership will be shared with others.

Add three files that were recently introduced in a refactoring,
that Malta emulation relies on. They are added by this patch
to Malta section, but they are not added to the general MIPS
section, since they are really not MIPS-specific, and there
may be some non-MIPS hardware using them in future.

There should be a person who will quickly evaluate new UI

something changes in UI.

The r4k machine was introduced in 2005 (6af0bf9c7) and its last
logical change was in 2005 (9542611a6). After that, one can
count 164 maintenance commits (QEMU API changes) with the
exception of 1 fix in 2015 (memory leak, commit 3ad9fd5a).
This machine was introduced as a proof of concept to run a MIPS
CPU. Two years later, the Malta machine was added (commit
5856de80), modeling a real platform.
Note also this machine has no specification except 5 lines in
the header of this file:
* emulates a simple machine with ISA-like bus.
* ISA IO space mapped to the 0x14000000 (PHYS) and
* ISA memory at the 0x10000000 (PHYS, 16Mb in size).
* All peripherial devices are attached to this "bus" with
* the standard PC ISA addresses.
The Linux kernel support for this machine has been dropped more
than 10 years ago in commit 302922e5.
It is time to deprecate this obsolete machine. Users are
recommended to use the Malta board, and its hardware is well
documented.

The script checkpatch.pl located in scripts folder was
used to detect all errors and warrnings in files:
hw/mips/mips_fulong2e.c
hw/isa/vt82c686.c
hw/pci-host/bonito.c
include/hw/isa/vt82c686.h
These mips Fulong 2E machine files were edited and
all the errors and warrings generated by the checkpatch.pl
script were corrected and then the script was
ran again to make sure there are no more errors and warnings.
